Subject: [PATCH v2 0/2] blk-mq: Allow to complete requests directly
Date: Mon, 18 Oct 2021 15:55:57 +0200 [thread overview]
Message-ID: <20211018135559.244400-1-bigeasy@linutronix.de> (raw)
v1…v2:
- Drop the SCSI patch for now.
- Make blk_mq_complete_request_direct() call the completion handler
directly instead going through struct chain (Jens and hch might had
the same in mind).
This series converts a part from the MMC layer which completes the
requests from kworker/ preemptible context. Its intention is to avoid
going through the softirq stack in preemptible context which would
involve the ksoftirqd in this case.
